Abstract

1528632 Timing ignition HONDA GIKEN KOGYO KK 18 Nov 1975 [28 Nov 1974] 47501/75 Heading F1B Control apparatus adapted to be interposed between an intake passage 1 of an internal combustion engine and a vacuum actuator 3, of a type employed for spark timing control, comprises a suction pipe 2 for connection to the engine intake passage, a control pipe 5 for connection to the vacuum actuator, a check-valve 6 providing the only communication between the suction pipe 2 and the control pipe 5 to permit flow toward the engine intake passage but to prevent reverse flow, a flow restrictor element 7 communicating with the control pipe 5 and means 8, 14 connecting the flow restrictor element to atmosphere, whereby in use of the apparatus high suction pressure in the engine intake passage opens the check-valve 6 to cause rapid actuation of the vacuum actuator 3 in one direction while low suction pressure in the passage causes the check-valve 6 to close, closing of the check-valve 6 permitting entry of atmospheric air through the flow restrictor element 7 to cause slow movement of the vacuum actuator in the other direction. The flow restrictor element 7 is of porous sintered metal.

Description

рез шток 14 св зана с поворотной пластиной 15 контактного прерывател  системы зажигани .The cutting rod 14 is connected to a rotary plate 15 of the contact chopper of the ignition system.

Обратный клапан 8 устроен таким образом, что он открываетс , когда разрежение во всасываклцей трубке 3 больше, чем в управл ющей трубке 4.The check valve 8 is arranged in such a way that it opens when the vacuum in the suction tube 3 is greater than in the control tube 4.

Регул тор работает следующим образом .The regulator works as follows.

о Когда разрежение во впускном трубопроводе 2 увеличиваетс , обратный клапан 8 открываетс  дл  увеличени  разрежени  в управл ющей трубке 4, в результате чего быстро срабатывает диафрагма 13, котора вт гивает шток 14. Это вызывает поворот пластины 15 по часовой стрелке. Однако когда разрежение во впускном трубопроводе 1 падает, обратный клапан 8 закрываетс , и атмосферный воздух no ступает в камеру 12 через дросселирук ций элемент 9 и воздушный фильтр 11. Это происходит относительно медленно из-за наличи  сопротивлени  создаваемого элементом 9, и следовательно , уменьшение разрежени  в управл ющей трубке 4 происходит постепенно , что вызывает заранее установленное запаздывание в перемещении штока 14 вакуумного механизма дл  поворота пластины 15 в направлении .против часовой стрелки.o When the vacuum in the intake manifold 2 increases, the check valve 8 opens to increase the vacuum in the control tube 4, as a result of which the diaphragm 13 is quickly actuated, which pulls in the rod 14. This causes the plate 15 to rotate clockwise. However, when the vacuum in the inlet pipe 1 drops, the check valve 8 closes and atmospheric air no longer enters chamber 12 through the throttling element 9 and the air filter 11. This occurs relatively slowly due to the presence of resistance created by element 9, and therefore reducing the vacuum in the control tube 4 occurs gradually, which causes a predetermined delay in the movement of the stem 14 of the vacuum mechanism for turning the plate 15 in the counterclockwise direction.

Следует отметить, что дросселирующий элемент 9 обеспечивает запаздывание срабатывани  вакуумного исполнительного механизма 6, но он не подвержен воздействию источника разрежени . Вместо этого он сообщаетс  с атмосферой дл  -впуска воздуха в управл ющую трубку 4.It should be noted that the throttling element 9 provides a delay in the operation of the vacuum actuator 6, but it is not affected by the vacuum source. Instead, it communicates with the atmosphere to inject air into control tube 4.

В этой конструкции, таким образом , предотвращаетс  закупорка элемента 9, котора  возможна в обычных регул торах.,In this design, the blocking of element 9, which is possible in conventional regulators, is thus prevented.

Когда разрежение во впускном трубопроводе велико, обратный клапан В открываетс  дл  быстрого уменьшени  разрежени , воздействующего на вакуумный механизм. Поток направл етс  от вакуумного механизма к впускному трубопроводу.When the vacuum in the intake manifold is large, the check valve B opens to quickly reduce the negative pressure acting on the vacuum mechanism. The flow is directed from the vacuum mechanism to the inlet pipe.

Благодар  тому, что дросселирующий элемент не имеет контакта с топливо-воздушной смесью двигател , не происходит его засорение во врем эксплуатации двигател .Due to the fact that the throttling element does not have contact with the engine air-fuel mixture, it does not clog during engine operation.
